780,000 is 780,820 rounded to the nearest ten thousand
Answer:
Step-by-step explanation:
rather than doing all of the sums, you should just learn the formula (for the pattern)
it is <u>n(highest + lowest)</u> where n is number of numbers
2
for example 2+3+4+5+6 = 20
<u>5(6+2)</u> = 20
2
~~~~~~~~~~~~~~~~~~~~
1+2+3+4+5+6+7+8 = 36
<u>8(9)</u> = 72/2= 36

Answer:
Step-by-step explanation:
Angle 4 is correspondin to 72 degrees, so angle 4 = 72
Angle 5 is supplementary to angle 4, so angle 5 is 180 - 72 = 108
Angle 6 is corresponding to 41 degrees, so angle 6 = 41
Answer:
x = -2, y = -9
Step-by-step explanation:
You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.
y = 2x -5 will become
4x - 1 = 2x - 5
Add 5 to both sides
4x + 4 = 2x
Subtract 4x from both sides
4 = -2x
Divide both sides by -2
-2 = x
Now we plug this number into an equation to find y.
y = 4x - 1 becomes
y = 4(-2) - 1
Simplifying it, we have:
y = -8 - 1
y = -9
Answer:
Equation: 2.75c + 3.59
Step-by-step explanation:
We know that she needs one bag of flour, so that's going to be the constant term. The constant is the one that remains the same, so in this case $3.59. 2.75 is being multiplied by c.
